Application filed. February 12, 1907. Serial No. 357,069.

county of London, England, electrical engiuser, have invented a certain new and useful Apparatus for the Production of Ozone, of W ich' the following is a full,' clear, and exact description, and for which ap lication for Letters Patent has been ma e in Great Britain, No. 3,905 of 1906, dated February 16, 1906.

This invention relatesto an improved electrical apparatus for the roduction of ozone.

It is Well known that in the production of ozone by existing apparatus, one pole of the oz omzer maybe sealed in vacuum or other wise, and operated in conjunction with an exposed metallic pole or electrode. In that form of ozonizer apparatus the exposed electrodes rapidly deteriorate through oxidat10 n, and objectionable gases such as nitrous oxrd are thereby roduced.

According to t e present invention both the poles or electrodes are hermetically scale by inclosing them in 'vacuo or'otherw se within suitable insulating. envelops whereby the air or other material containing oxygen to be ozonizd does not come into contact with the electrodes.

The invention is hereafter described with reference to the accompanying drawings, in which Figure 1 is an elevation of the improved a paratus complete, the sealed tubes being s own in longitudinal section. Fig. 2 is a cross section on line 22 of Fig. 1. Fig. 3 is a longitudinal section of a second form of tubular envelops for the electrodes, and Fig. 4 1s a transverse section on line 4 4 of-Fig. 3. Flg. 5 IS an end view of a third form of tubular envelop. Fig. 6 is'a longitudinal section of Fig. 5 on the line 66.

A source of electric supply such as an accumulator or a magneto generator is employed to supply current of the required tension to the electrodes of the apparatus.

In the drawings anaccumulator A rovided with terminals a a is connects by means of conductors or leads a a to an induction coil or transformer B having rimary terminals 6 b The coil B is provi ed r with high tension terminals 1)" b to which-are connected the high'tension leads b I). l The lead 6 isc'onnected electrically at the joint d to an electrode (1? which is hermetically in-' I Specification of Letters Patent.

closed in an envelo D of suitable insulatin material. The lea b is similarly connecte by means of a joint 0 to an electrode a which is likewise hermetically inclosed within an insulating envelop C.

' In Figs. 1 and 2 the envelop C is shown as an annular tube which may for instance be made of glass and the envelop D is shown as a cylindrical'tube which also may be of glass arranged concentrically within the annulus O and separated therefrom by means of studs,

projections or the like distance-pieces d arranged at intervals along the length of: the device. In this way space is left between the tubes 0 D through which air or other matter to be 'ozonizedis assed by any suitable apparatus. In the rawings is shown a blower consisting of a fan E mounted on a spindle e and journaled in a casing F having a cone-shaped mouth f leading to the tube C. This blower serves to direct a current of air through-the space between the tubes C I) and this air is accordingly ozonized and driven out at the opposite end of the annular passage (as shown by the arrows in Fig. 6) when the high tension current asses from the one electrode a to the sec'on one (P. A rubber or other socket piece G may be employed to connect the mouth. f to the tube O as shown in Fig. 1.

The tubes O and D have been describedv as being hermetically sealed so as to preserve the electrodes therein from contact with the air; they may if desired both be exhausted in any-usual manner so that a vacuum of suitable tension is afiorded therein and the degree of vacuum may be the same in both tubes or otherwise as preferred.

In the form illustrated in Figs. 3 and 4 the envelops C D are of flat tubular section and superposed in any desired number. These envelops C C and D D are separate and are maintained apart by distance pieces d The electrodes 0 (1 which are hermetically sealed in the flattubes O O D D are connected as before to the leads I) I) and where a number of electrodes 0 or d are employed they are connected to ether in parallel.

In a third form of t e invention shown in Fig. 5, the electrodes 0 D assume the form of tubes of equal diameter andgare arranged in a circle about the central air passage which in this arrangement is of cylindrical bore.

In lieu of the accumulator shown in Fig. 1 any othersource of current may be employed able material and are conveniently made of minals a a may be connected thereto and again the blower E may be actuated by the electric supply. 10 I The distance pieces (1 may be made of glass, vulcanite 'or other insulating material.

The electrodes are constructed of any suitcopper gauze. The tubes or envelops may with advantage be exhausted to a vacuum obtainable by a mercury ump.

In Figs. 5 and 6 the air from-the blower passes between adjacent tubes G D into the central cylindrical passage as represented by the arrows. Having thus described my invention what I claim as such and desire-tosecure by Letters Patent, is:
